Supporter for a human body and bed equipment using the same

Abstract: Lengthy plates 32 are inserted between front end parts 34b formed by inwardly bending lengthy sacks 34 at the front parts and base parts 34a thereof, and belts 33 are inserted into insides of the front end parts 34b. Next, the plates 32 are drawn out from the sacks 34, and are caught by hooks 21 furnished at the lower parts of suspending strings 19A, 19B, 19C, 19D. Subsequently, a motor is driven to coil up the suspending strings 19A to 19D on drums 11A, 11B, 11C, 11D, so that a patient on the belts 33 is lifted, and a hammock 20 is spread on a bed 10. Then, the motor is reversely rotated to uncoil the suspending strings 19A to 19D to land him on the hammock 20, and the hooks 21 are taken out from the belts 33 and engaged with the hammock 20. The motor is again driven to coil up the suspending strings 19A to 19D, so that the patient is lifted from the bed 10 by the hammock 20 and is taken to a bathtub.

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a supporter for a human body and a bed equipment using the same, which change postures of a patient lying on a bed, or take him to a bathtub or toilet. BACKGROUND OF THE INVENTION The same applicant proposed a bed equipment which suspended a serious patient who could not move by his own ability through a hammock and took him to the bathtub or toilet near his bed (U.S. Patent No.5,072,840 corresponding to Japanese Patent Laid Open No.3-202059). The present bed equipment spreads the hummock between the bed and the patient lying thereon, lifts up the hammock with the suspending belts, and moves the hammock in directions crossing the bed to carry him above the bathtub or toilet for having a bath or easing nature. After having used the bath or toilet, he is again taken back to the bed and laid thereon. The proposed bed equipment has, as disclosed in Fig.5 of said publication, a merit that it has a instrument for raising and laying the upper half of the patient's body, whereby he may be taken to the bathtub or toilet in an easy posture and taken back onto the bed therefrom. However, the proposed bed equipment has left big unsolved problems, that is, how the hammock is spread between the bed and the patient lying thereon, and how it is removed therefrom after he has been taken back onto the bed. Such problems have been outstanding not only in the above mentioned bed equipment proposed by applicant, but in existing bed equipment. Since the problems have remained unsolved, nurses held up the patient in their arms from the bed when the hammock was laid on the bed or removed therefrom. However, this work was very heavy, and when changing clothes of the patient lying on the bed, the nurse raised the patient from the bed. This was also a heavy labour. In addition, as the patient usually lay on his back (facing upward), he had to often change his postures. The nurse let him lie on his side, patted over his back or let him watch television. The changing of his posture was also a hard work. The GB-A-1 458 175 describes a lifting device comprising a hollow member with a removable protective covering. The protective covering has a first portion which during lifting covers a portion of the exterior of the hollow member, wherein the inside surface of the protective covering is turned outwardly, whilst another portion of the protective covering extends into the channel of the hollow member. In use, a driving stick is pushed into the channel of the hollow member such that the hollow member rolls under the body of a patient. In this situation the protective covering is intended to prevent any direct contact between the surface of the hollow member with the body of the patient in order to avoid any contamination of the hollow member. After use, the protective covering is removed from the hollow member and discarded so that the hollow member can be used again with new protective covering. If the person is to be moved from the bed, a belt or hammock must be positioned by hand below the patient. After the lifting action the belt or hammock can be fixed to lifting devices for moving the patient to some other location. DISCLOSURE OF THE INVENTION It is a first object of the present invention to provide a supporter for a human body which can easily change the posture of the patient laying on the bed. It is a second object of this invention to provide a bed equipment which can easily spread the hammock between the bed and the patient thereon, and can easily remove it therefrom. The present invention provides a supporter for a human body comprising the features of claim 1. This invention also provides bed equipments comprising the features of claims 3 and 5. In the above stated structure, if serving the lengthy plate 32 as an assistant means for interposing the belt 33 under the patient, inserting the supporter 31 between the bed 10 and the patient lying thereon, and coiling up the suspending strings 19A, 19B, 19C, 19D so as to raise the patient from the bed 10, the hammock 20 can be easily spread on the bed 10. If the patient is similarly lifted therefrom, the hammock 20 can be easily removed from the bed 10. Further, if the belts 33 are moved upwardly at the one sides by coiling up the suspending strings 19B, 19D, the patient lying on his back can be changed to lie on his side. If the patient's posture is changed to be on his side, the nurse can easily change the clothes and pat on his back, and he can watch TV 51 by the posture lying on his side.

The supporter for a human body will be stated, referring to Figs.1, 2, 3 and 4. Fig.1 is the perspective view thereof. The supporter 31 for a human body comprises the lengthy plates 32, the belts 33 and the lengthy sacks 34. The lengthy plate 32 is formed by bending its horizontal part 32a in the end portion 32b as a handle to be held by fingers. The plate 32 is made of a material having elasticity and strength such as a metal plate. The belt 33 is a synthetic resin or a cloth, and is formed with holes 38 at both ends which, as later stated, will be caught by hooks 21 provided in the lower ends of the suspending strings 19A, 19B, 19C, 19D. The sack 34 is fabricated with such a material of high strength and low coefficient of friction such as Nylon. The sack 34 is furnished with a handle 39 on an end around an opening 36 thereof. A front end portion of the sack 34 is also an opening 37. The plate 32, belt 33 and sack 34 are made of such materials of water repellency (a property shedding water), so that they do not impregnate the water when immersing in the bathtub. Fig.2(a), (b), (c) show a method of making the supporter 31. Fig.2(a) shows the cross section of the sack 34 before the make-up. As illustrated, both ends of the sack 34 are the openings 36, 37. As seen in Fig.2(b), the front ends 34b are at first folded back inwardly of the base end portion 34a. An arrow mark A shows a folding back direction (also refer to a partially enlarged part). The front end portion 34b is further folded back inwardly, and, as in Fig.2(c), drawn out leftward from the opening 36 of the base end portion 34a. Fig.2(c) shows the cross section of the sack 34 which has been drawn out. As will be explained later referring to Figs.3 and 4, the handle 39 is held by the hand, and the plate 32 is inserted between the base end portion 34a and the front end portion 34b from the opening 36 as shown with an arrow B, and the belt 33 is inserted into the inside of the front end portion 34b from the opening 37 as shown with an arrow C. A using method of the supporter 31 will be stated referring to Figs.3 and 4. Fig.3(a) to (e) depict a method for interposing the supporter 31 between the bed 10 and the back of the patient lying thereon. As seen in Fig.3(a), the end portion 32b of the plate 32 is held with one hand, while the handle 39 is held with the other hand, and the horizontal part 32a of the plate 32 is inserted from the opening 36 between the front end portion 34b of the sack 34 and the base end portion 34a formed by turning back the end portion 34b inwardly. Then, the belt 33 has been interposed inside of the front end 34b from the opening 37 (also refer to Fig.2(c)). The patient is illustrated as being up by a gap G from the upper surface of the bed 10 for convenience of explanation, however actually he is just on the bed 10. When the horizontal part 32a is inserted in a direction N11 as depicted in Fig.3(b), the front end portion of the belt 33 slowly goes ahead between the bed 10 and the patient. At this time, as shown with Q1 in a partially enlarged part, the sack 34 is gradually turned back outwardly and interposed between the bed 10 and the patient. When the front end part 33a of the belt 33 is drawn leftward from the left end of the sack 34 as shown in Fig.3(c), the front end 33a is held with the fingers to further pull out the belt 33 in the direction N11. In such a way, the belt 33 is inserted between the bed 10 and the patient, and the plate 32 is got out in a direction N12 as shown in Fig.3(d), (e). As seen from the above, the lengthy plate 33 serves as the assistant instrument for placing the belt 33 between the bed 10 and the patient. When the belt 33 and the sack 34 are positioned between the bed 10 and the body, the holes in both ends of the belt 33 are, as seen in Fig.3(f), engaged with hooks 21 held at the lower ends of the suspending strings 19A, 19B, or the suspending strings 19C, 19D. A motor is subsequently driven to coil up the strings 19A, 19B, 19C, 19D, so that the patient is raised from the bed 10, and then the patient is moved in a direction (an arrow N13) crossing the bed 10 to the bathtub or toilet. A work after having raised him from the bed 10 will be later mentioned referring to Figs.8 to 10. A further reference will be made with Fig. 4 to a method of taking out the belt 33 and the sack 34 between the bed 10 and the patient. Fig.4(a) shows, similarly to Fig.3(f), that after having lifted the patient from the bed 10 to take him to the bathtub or toilet, he is again taken back above the bed 10 and moved down thereon. Fig.4(a) shows the same condition as in Fig.3(e). A left end portion 341a of the sack 34 is held with one hand as seen in Fig.4(a), while the right end portion 33b of the belt 33 is held with the other hand. If the belt 33 is pulled in a direction arrowed with N14 as illustrated in Fig.4(b)(c), the belt 33 is drawn out from the sack 34. If a right end portion 341b of the sack 34 is held with the fingers as seen in Fig.4(d)(e) and pulled in an arrow N15, the sack 34 is gradually turned back in an arrow Q2, and drawn out from the body and the bed 10 (refer to a partially enlarged part). When inserting the belt 33 and the sack 34 between the patient and the bed 10 as illustrated in Fig.3, or taking out them therefrom as illustrated in Fig.4, the outer surface of the sack 34 which is being turned back in the arrow Q1 (refer to the partially enlarged part of Fig.3(b)) or in the arrow Q2 (see the partially enlarged part of Fig.4(d)) slightly touches the patient on his back, and accordingly no pain is given to him. He strongly presses his back to the upper surface of the bed 10, and does not strongly press his waist, hip and legs thereto. It is, therefore, possible to easily insert the belt 33 under the hip or legs, and easily take it out if not depending upon the manners of Figs.3 and 4. A further reference will be made with Figs.5 to 10 to the bed equipment where said supporter 31 is used. Fig.5 is the plan view of the bed equipment, and Fig.6 is the front view of the same. In Fig.5, there are provided in parallel four rails 2A, 2B, 2C, 2D between a left frame 1A and a right frame 1B. The frames 1A and 1B are mounted thereon with rotation shafts 3A and 3B which are provided with rollers 4 moving on a guide rail 5A provided outside of the frame 1A and outside of the other frame 1B. In the under stated explanation, the length of the guide rails 5A, 5B is X direction, while the direction transverse with the X direction is Y direction. In Fig.5, one rotation shaft 3A is provided with a sprocket 6, and a first motor M1 is provided between the rail 2B and the rail 2C. The rotation shaft of the first motor M1 is provided with a sprocket 7. A chain 8 is bridged between the sprockets 6 and 7. When the first motor M1 is driven, the rotation shaft 3A and the roller 4 rotate on the guide rails 5A, 5B, and the frames 1A, 1B move in the direction X along the guide rails 5A, 5B. The rotation shafts 3A and 3B are connected, and the rotation shaft 3A is rotated by the first motor M1, and when the rollers 4 at both ends of the rotation shaft 3A rotate on the guide rails 5A, 5B in the direction X, the rollers 4 at both ends of the other guide rail 5B also rotate on the guide rails 5A, 5B in the direction X. In other words, the motor M1, rollers 4 and guide rails 5A, 5B serve as the crossing instruments for moving the hammock (later mentioned) carrying the patient in the direction transverse with the bed 10 (the direction X). In Figs.5 and 6, there are provided four drums 11A, 11B, 11C, 11D between the frames 1A and 1B. The drums 11A, 11B are coiled thereon with the first suspending strings 19A, 19B, while the drums 11C, 11D are coiled thereon with the second suspending strings 19C, 19D. Each of the drums 11A to 11D is furnished on the rotation shaft 12 carried by bearings 29. The drum 11A is rotated by a second motor MA2, sprockets 26, 27 and a chain 28, and similarly the other drums 11B, 11C, 11D are also driven by the second motors MB2, MC2, MD2, sprockets 26, 27 and a chain 28, respectively. In Figs.5 and 6, inside of the frame 1A, fixed pulleys 13A are provided, and inside of the frame 1B, fixed pulleys 13B are provided. These fixed pulleys 13A, 13B are secured to the frames 1A, 1B via not shown bearings. In Fig.5, a first feed screw 14A is furnished between the rails 2A and 2B, and a second feed screw 14B is furnished between the rails 2C and 2D. The first feed screw 14A is defined in the right side with a rightward screwthread 141A on which a first nut 15A is screwed, while the first feed screw 14A is defined in the left side with a leftward screwthread 142A on which a second nut 15C is screwed. The second feed screw 14B is also defined with a rightward screwthread 141B and a leftward screwthread 142B which are respectively screwed with a third nut 15B and a fourth nut 15D. As seen in Fig.5, pitches of the rightward screwthreads 141A and 141B are larger than those of the leftward screwthreads 142A and 142B. Each of the nuts 15A to 15D is provided with the rotation shaft 16 which is provided with the roller 17 and the movable pulley 18. The rollers 17 are carried on the rails 2A, 2B, 2C, 2D. In Figs.5 and 6, the first suspending strings 19A, 19B mounted on the drums 11A, 11B are associated with the fixed pulley 13B and the movable pulley 18, and the first strings 19A, 19B have hooks 21 at the lower ends for holding the right end portions (the part of the patient's head) of the hammock 20. On the other hand, the second suspending strings 19C, 19D mounted on the drums 11C, 11D are also associated with the fixed pulley 13A and the movable pulley 18, and the second strings 19C, 19D have hooks 21 at the lower ends for holding the left end portions (the part of the patient's legs) of the hammock 20. The hammock 20 is preferably formed in net with the water repellent material not to impregnate the water when immersing in the bath. In Fig.5, there is provided a third motor M3 between the first feed screw 14A and the second feed screw 14B, and sprockets 23 are furnished on the right ends of the first and second feed screws 14A and 14B. The rotation shaft of the third motor M3 is mounted thereon with a sprocket 24, and a chain 25 is bridged between the sprockets 23 and 24. Accordingly, when the third motor M3 is driven, the feed screws 14A and 14B rotate synchroneously. When the feed screws 14A, 14B rotate, the nuts 15A to 15D move in the direction Y along the feed screws 14A, 14B. The rightward screwthreads 141A, 141B and the leftward screwthreads 142A, 142B are threaded in opposition respectively. In such a way, if the motor M3 normally rotate in Figs.5 and 6, the nuts 15A, 15B on the right side move leftward,and the nuts 15C, 15D on the left side move rightward, and vice verse . Then, the movable pulleys 18 integrally provided to the nuts 15A to 15D move in the same direction as the nuts 15A to 15D. Since the pitches of the right screwthreads 141A, 141B are larger than those of the left screwthreads 142A, 142B, the right nuts 15A, 15B move faster in the direction Y than the left nuts 15C, 15D. Fig.6 illustrates that with respect to the first suspending strings 19A, 19B and the second suspending strings 19C, 19D lifting the hammock 20 as shown with the chain line, the motor M3 normally rotates, so that the nuts 15A, 15B and the nuts 15C, 15D approach, and with respect to the first suspending strings 19A, 19B and the second suspending strings 19C, 19D as shown with the dotted line, the motor M3 rotates reversely, so that the nuts 15A, 15B and the nuts 15C, 15D separate. That is, the feed screws 14A, 14B, the nuts 15A to 15D, and the motor M3 serve as approaching or separating the first suspending strings 19A, 19B and the second suspending strings 19C, 19D each other. Said approaching or separating thereof are for raising or laying the upper half part of the patient on the hammock 20. For lifting the patient lying on the bed through the hammock 20, the first strings 19A, 19B and the second strings 19C, 19D are gradually approached, thereby to raise his upper half part. For landing him lifted in the hammock onto the bed 10, the first strings 19A, 19B and the second strings 19C, 19D are gradually separated, thereby to lay his upper half part. Further, the first strings 19A, 19B and the second strings 19C, 19D can be independently coiled up or uncoiled down by driving the second motors MA2, MB2, MC2, MD2. In Figs.5 and 6, if normally rotating the second motors MA2, MB2, MC2, MD2 so as to normally rotate the drums 11A, 11B, 11C, 11D, the suspending strings 19A, 19B, 19C, 19D are uncoiled from the drums 11A to 11D, so that the hooks go down, and on the other hand, if reversely rotating the second motors MA2, MB2, MC2, MD2 so as to reversely rotate the drums 11A, 11B, 11C, 11D, the suspending strings 19A, 19B, 19C, 19D are coiled on the drums 11A to 11D, so that the hooks go up. The present bed equipment is composed as said above, and an explanation will be made to the using manner of this bed equipment. When the bed equipment is not used, all the strings 19A to 19D are coiled up as shown with the solid line in Figs.6 and 7, so that the hooks are at the high position. A reference will be made with Fig.8(a)(b)(c) to the method of spreading the hammock 20 between the bed 10 and the patient thereon. The second motors MA2, MB2, MC2, MD2 shown in Fig.5 are normally rotated to draw out all the suspending strings 19 A to 19D coiled on the drums 11A to 11D and move down the hooks 21 from the position shown with the solid line to the position shown with the chain line in Fig.8(a). Next, the belt 33 and the sack 34 are interposed between the bed 10 and the patient as explained referring to Fig.3. When having placed the belt 33 and the sack 34, the hooks 21 are caught by the holes 38 in both ends of the belt 33 (see the chain line in Fig.8(a)). The belts 33 are used two in total for the head and the leg parts. The belt 33 for the head part is engaged at both ends with the hooks 21 of the first strings 19A, 19B, and the belt 33 for the leg part is engaged at both ends with the hooks 21 of the second strings 19C, 19D (also see Fig.6). The motors MA2 to MD2 are reversely rotated as shown in Fig.8(b) to move up the hooks 21 so that the patient is lifted up around 20 to 30 cm. If thus supporting the patient, the hammock 20 can be easily spread on the bed 10 (see Fig.8(b)). If the motors MA2 to MD2 are normally rotated, the hooks 21 are moved down to lay him on the bed 10, and all the hooks 21 are removed from the belts 33 and thereafter the hooks 21 are engaged with the hammock 20 at the four corners (Fig.8(c)). The work for spreading the hammock 20 between the bed 10 and him is accomplished. A next explanation will concern the method of taking him to the bathtub nearby the bed 10 with the hammock 20. Fig.6 shows with the dotted line that the hammock 20 is laid under him lying on the bed 10 as seen in Fig.8(c). Then, if the motor M3 (Fig.5) is driven to rotate the feed screws 14A, 14B, thereby to approach each other the nuts 15A, 15C and the nuts 15B, 15D, the left movable pulley 18 and the right movable pulley 18 are approached each other as shown with the chain line in Fig.6, and at the same time, the motors MA2 to MD2 are driven to rotate the drums 11A to 11D, and if coiling up all the strings 19A to 19D, the patient is lifted from the bed 10 as raising his upper half part as shown with the chain line in Fig.6. Fig.9 shows with the solid line the front view that he is lifted from the bed 10 in such a manner. Subsequently, if the motor M1 (see Fig.5) is driven, the rollers 4 move on the guide rails 5A, 5B in the direction transverse with the bed 10 (direction X), so that he is moved above the bathtub 50 (refer to the chain line in Fig.9). The motors MA2 to MD2 are normally rotated to move down the hammock 20 and take him into the bathtub 50. The motor 3 is then not driven, so that the distances between the nuts 15A, 15B and the nuts 15C, 15D, i.e., the distances between the first strings 19A, 19B and the second strings 19C, 19D are fixed, and he is taken down into the bathtub 50 as raising his upper half part as seen in Fig.9. For bathing his body, the hooks 21 are taken off from the hammcok 20, and the hammock 20 is removed from the tub 50. Having bathed, the belts 33 are placed under his body in the tub 50. The belts 33 are inserted in the sacks 34 with both ends of the belts 33 drawn out from the sacks 34. Next, the hammock 20 is put under the belts 33, and the hooks 21 are set in the hammock 20. The lengthy plate is not required at this time. The motors MA2 to MD2 are reversely rotated to lift up the hammock 20 and take him out from the tub 50. Fig.10 illustrates this condition. The nurse wipes him with a towel. The belt 33 and the sack 34 are water repellent, and since the hammock 20 is in net, the water hardly goes into it. The motor M1 is reversely rotated to move the rollers on the guide rails 5A, 5B which carries the patient above the bed 10. The condition at this time is the same as shown with the chain line in Fig.6. The motors MA2 to MD2 are driven to move him down. If rotating the motor M3 reversely to the above, the movable pulleys 18 move from the position shown with the chain line in Fig.6 to the position shown with the solid line. Since the first suspending strings 19A, 19B and the second suspending strings 19C, 19D separate each other, the patient's upper half part falls backward, and he may lay on the bed 10 with ease as shown with the solid line in Fig.6. The state as this time is the same as shown in Fig.8(c). All the hooks 21 are removed from the hammock 20, and are thereafter set into the holes 38 in both ends of the belts 33. The motors MA2 to MD2 are driven to lift the patient from the bed 10 by the belts 33. This state is the same as shown in Fig.8(b). Then, the hammock 20 is removed from the bed 10. The motors MA2 to MD2 are driven to again take him onto the bed 10. This state is the same as shown in Fig.8(a). All the hooks 21 are taken out from the belts 33, and the belts 33 and the sack 34 are removed from the bed 10 and the patient. This removing method is the same as having mentioned with Fig.4. In this way, the bathing is finished. The work of taking him to the toilet for easing nature is basically the same as taking the bath, and an explanation therefor is omitted. Another using method of the supporter 31 will be stated with reference to Fig.11(a)(b). Fig.11(a) shows that the belt 33 is inserted between the bed 10 and the patient. This condition is the same as shown with the chain line in Fig.8(a). If the motors MB2, MD2 (Fig.5) of the one side are driven to lift up only the left strings 19B, 19D, the patient is made lie on his side as seen in Fig.11(b), he can watch TV placed by the bed 10. In such a posture, the nurse can pat him on the back, and his clothe can be easily changed. If the motors are reversely rotated, the patient lies on his back as seen in Fig.11(a). This supporter is used in various ways as above set forth. Another exmodiment of the supporter will be mentioned. Fig.12 is the perspective view of another embodiment of the supporter. This supporter 61 comprises lengthy plates 62 and lengthy sacks 64. The plate 62 is shaped in L having a horizontal part 62a and a bent part 62b, the horizontal part 62a being formed at its front end with a hole 63 for catching a hook 21. The sack 64 is inwardly turned back at the front end 64b which is opend with a hole 65 for inserting the hook 21. Fig.13 (a) (b) illustrate the method of turning back the sack. Fig.13(a) is a cross sectional view of the sack before it is turned back, and Fig.13(b) is a cross sectional view after the sack 64 has been turned back at the front end. In Fig.13(a), if turning back the front end 64b inwardly as shown with the chain line A, this end portion 64b is projected from an opening 66 of a base end 64a as shown in Fig.13(b). Fig.12 depicts the sack 64 which has been inwardly turned back at the front end as shown in Fig. 13(b). The lengthy plate 62 is inserted at the front end portion between the base end 64a and the front end 64b from the opening 66. The using manner of this supporter 61 will be concerned. Fig.14(a)(b)(c) show the method of interposing the supporter 61 between the bed 10 and the patient's back. As shown in Fig.14(a), the base end part 64a is held at an end 641a with the fingers of one hand and the plate 62 is held at the bent part 62b with the fingers of the other hand, and the horizontal part 62a is inserted at the end part 621a between the base end part 64a and the front end part 64b (see an arrow N3). Fig.15 illustrates the plate 62 shown with the solid line in this condition. The horizontal plate 62a is, as shown in Fig.14 (b), further inserted in the direction N3 between the body and the bed 10, so that the front end portion 621a of the horizontal part 62a is projected toward the right side of the body (Fig.14(c)). The hook 21 is inserted into the hole 63 formed in the horizontal part 62a and the hole 65 formed in the front end part 64b. The chain line of Fig.15 shows the condition of Fig.14(c). When the motors MA2, MC2 (Fig.5) are driven to coil the suspending strings 19A, 19C on the drums 11A, 11C, the hook 21 is lifted up from a position a to a position b , and the body is turned 90° in an arrowed direction N4. If the patient's posture is changed from a supine to a sideway, the nurse can touch his back or change his clothe. In addition, he can watch TV 51 or take a meal as having changed his lying position. For taking him to the bathtub or the toilet, the motors MA2, MC2 are further driven to coil the strings 19A, 19C on the drums 11A, 11C, so that the hook 21 is moved up to a position c in Fig.15. Thus, the his body is, as seen in Fig.16, lifted up from the bed 10. Then, he is moved horizontally in an arrow N5 to the bathtub 50 or the toilet (not shown here) (see Fig.16). For returning the lifted patient onto the bed 10, when the motors MA2, MC2 are reversely rotated, the hook 21 goes down from the position c to the position b , and he is landed on the bed 10. If further rotating the motors MA2, MC2, the lengthy plate 62 is rotated in an arrow N6, and the hook 21 goes down to the position a , so that he again looks upward on the bed 10. Fig.17 illustrates a method of taking out the plate 62 and the sacks 64 from his back and the bed 10. As shown, if the sack 64 is held at the front end 64b with the fingers and pulled in a direction N7, the plate 62 is also moved in the same, so that the plate 62 and the sack 64 are taken out from him and the bed 10. In this case, it is allowed that the bent part 62b is held with the fingers and the plate 62 is moved in the direction N7, and the horizontal part 62a is removed therefrom, and after that, the sack 64 is held at the front end 64b with the fingers and the sack 64 is removed therefrom. The sack 64 functions as follows. Without the sack 64, only the lengthy plate 62 is pushed between the body and the bed 10, the horizontal part picks at the patient's back with its front end, or the horizontal part 62a rubs his back, and he feels a physical pain. In particular, as a serious patient often lies unclothed on the bed 10, if a naked horizontal part 62a stripped of the sack 64 is pushed between the body and the bed 10, the horizontal part 62a touches his back at its front end, and a big pain is given. If a patient is an old man, his skin is flabby, its end portion easily bites him. When the horizontal part 62a is taken out therefrom as shown in Fig.17, it rubs his loosened body if without the sack 64, and the patient feels a big pain about his body. For giving no pain as stated above, the plate 62 is covered with the sack 64 and interposed with the horizantal part 62a between the body and the bed 10. Thus, placing the sack 64 between the patient's body and the bed 10, when interposing the horizontal part 62a as shown in Fig.14, or taking out it therefrom, neither it bites nor rubs his back, and the horizontal part 62 may be served as said above. Only the supporter 61 may be used as a means for changing the lying postures. In this case, as shown in Fig.18, the hook 21 is not used, and the patient's lying position is changed sideways by the supporter 61, and the supporter 61 is raised by the nurse's hand 52. While keeping his posture as it is, she may pat on his back or change his clothe, or lets him watch TV 51. Further, as seen in Fig.19, the bent part 62c may be shaped in U, whereby the patient can be supported securely. In dependence upon the present invention as stated above, it is possible to spread the hammock 20 between the bed 10 and the patient or remove it therefrom. In addition, it is possible to change his lying positions on the bed 10, change the clothe, let him watch the television 51 or for the nurse to touch the patient's back.
